多媒体是教学过程的基本要素。它作为传递教学信息的媒介,能把抽象的教学内容化为直观的教学信息。因此优化教学过程必须先优化媒体设计,教学实践表明,在生物教学过程中对多媒体进行优化设计,更能优化生物教学。生物教学强调情境与协作,重视直观与操作,提倡学生学习的主动性。将带网络功能的多媒体计算机引入生物课堂,具有特殊的优越性。 Multimedia is a basic element of the teaching process. As a medium to transmit teaching information, it can turn abstract teaching into intuitive teaching information. Therefore, optimizing the teaching process must first optimize the media design, teaching practice shows that in the biological teaching process to optimize the design of multimedia, to optimize biological teaching. Biology teaching emphasizes situations and collaboration, attaches importance to intuition and operation, and promotes student learning initiative. The introduction of multi-media computer with network function into biology class has special advantages.
